If you watch the show carefully, you can usually see the wires holding the things up.
Helium is the element commonly used to expand small objects and make them float. Its low density allows it to lift objects, such as balloons, creating the buoyant force necessary for them to rise in the air.
Objects that are denser than water will sink, such as rocks, metal objects, and certain types of wood. Objects that are less dense than water will float, such as plastic bottles, rubber ducks, and foam.
Sparkling water contains carbon dioxide gas that creates bubbles. These bubbles attach to objects, making them buoyant and causing them to float. The bubbles decrease the density of the water, allowing objects to float more easily.
Objects can float when they are less dense than the liquid they are placed in. This creates an upward force called buoyancy that helps keep the object afloat. By adjusting the weight or shape of an object, you can make it float in water or other liquids.
In a vacuum, there is no air or other medium for objects to displace, so there is no buoyant force to make them float. Objects in a vacuum will simply remain in place if they are not acted upon by any external forces.
You can't make a bar of metal float on water, but boats with metal hulls float. Also, metal bars and other metal objects float on mercury.
Because it is more dense
Yes, salt can make water denser, causing objects to float more easily.

It depends on the buoyancy of an object in relation to the liquid it is in.
objects float better because chemicals help make the objects float higher. the more salt the higher the things go

Objects that are less dense than the environment in which they are immersed will float, unless they are tethered.
Objects that float in water have a lower density than water. -anonymous18_K
